I've been trying to solve a home network issue. Sorry if this is a little convoluted.

The internet connection is through a Motorola DSL modem. The connection works. When I connect the modem to a WRT54g wireless router's internet port, I cannot connect to the internet. When I connect the modem to one of the other four ports, the connection works. Unless I have a second computer on the network, then there is an IP address conflict.

The Modem is using DHCP to assign the same IP to both computers. What settings do I need to use to connect multiple computers?

Modem Name Motorola
